Where to now with Ich treatment?

[D70Challenger]

Hello all, My yellow tang and 2 clowns have grown Ich over the past week. I have a 72 gal bowfront with a 20 gal sump. I did a 15 gal water change a few days ago and bought a medication "Ich-X." the Ich-X is supposed to treat up to 240 gal and ive used almost all with no hope so far. At the moment i do not have coral but do have inverts such as shrimp, lots of crabs, lots of snails and a feather duster. last night my tang began scratchign alot so i tried taking more drastic measures and removed the tang and clowns and placed them in a 5 gal styrafoam container for about an hour with a higher temp and a high dose of the medication. when i took the fish out they seemed to be on the brink of death, (clowns laying on sand, and tang being pale as a ghost) but over the day they have regained all colour and energy. their Ich spots seem to have greatley diminished but i know they still are infected. i need to know what can i do to save them for sure. unfortunatley i do not have an additional tank or anything to quarantine the fish for long. I saw on the sticky that i can try a hyposalinity solution but it said it would kill all rocks and inverts. any help would be appreciated. i just seem to have came to a halt as i lack the tools to properly cure them. i feel however long i help them fight it the Ich will eventually previal and take the fish.

I think if you tried to cook me and used a quack chemical on me, I'd be close to death to.

There are only a few known methods to treat Marine Ich. There are no short cuts or miracle drugs.

You first begin by reading, then following the guidelines in this post:
Curing Fish of Marine Ich

The process is straight forward, but there are no deviations from it. Fish must be moved out to a hospital tank and treated there. No alternatives to this, if you plan on treating your fish, at all.

Ya i wont be tryign what i did again. I was following the directions on the bottle and what the shop owner told me, then i read that and was like, "wow i feel like a fool now." I have an old 24 gal nano cude in my garage, i could try setting that up and hopeing that works. how do i filter that water with no biological filters such as rock, sand, or plants? any advice on how to set up the hospital tank correctley. i dont want to under do it to where they get poisened by dirty water.

No worries. Most of these sorts of things comes from bad advice.

The best advice I can offer is to do reading. I can point you to what to read, but the reading is for you:
A Fish Quarantine Process

The quarantine and hospital tanks are essentially the same for your purpose.
